How to associate a price level with a SharpDX Y level?

I've begun using SharpDX to plot text on a chart. One thing I can't figure out is how to plot to a particular price level on the chart. SharpDX deals in pixels, I believe. How is this conversion done?

I found the answer:

protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
{
int yLevel = chartScale.GetYByValue(17850); // Price level is 17850

....

SharpDX.RectangleF rectangleF = new SharpDX.RectangleF(startPoint.X, yLevel, ChartPanel.W, ChartPanel.H);
}
